[0053] In the related technical field of scrubber, with the continuous friction of rolling brush and scraping plate, wear will occur, which will cause the diameter of the rolling brush to decrease, thereby causing the scraping plate to be unable to effectively remove the dirt on the rolling brush. At the same time, the decrease of the diameter of the rolling brush causes the overall scrubber to move downward, resulting in more contact between the scraping strip and the ground, and the friction between the scraping strip and the ground is larger, making it difficult for the scrubber to move.

[0054] Based on this technical problem, the following embodiments are proposed.

[0055] Example 1

[0056] like Figures 1-2 As shown, this embodiment proposes a scraper and scraper linkage assembly for a floor scrubber. The floor scrubber is equipped with a frame 5, and the scraper and scraper linkage assembly includes:

[0057] A roller brush 1 is rotatably mounted on the frame 5;

[0058] Scraper 2 is rotatably mounted on the frame 5 and has an elastic element 12. One end of the elastic element 12 is connected to the scraper 2 and the other end is connected to the frame 5. The scraper 2 is kept in contact with the outer peripheral surface of the roller brush 1 under the action of the elastic element 12.

[0059] Scraping condition 3, which is rotatably mounted on the frame 5, and is in contact with the ground for scraping the ground;

[0060] Transmission mechanism 4, which includes a first transmission unit and a second transmission unit that are in transmission cooperation. The first transmission unit is in transmission cooperation with the scraper 2, and the second transmission unit is in transmission cooperation with the scraper 3.

[0061] The scraper 2, the scraping condition 3, and the transmission mechanism 4 are designed such that when the diameter of the roller brush 1 decreases, the scraper 2 rotates under the force of the elastic member 12 and remains against the outer circumferential surface of the roller brush 1, and drives the first transmission unit to rotate. The rotation of the first transmission unit drives the second transmission unit to rotate, and the rotation of the second transmission unit drives the end of the scraping condition 3 in contact with the ground to move upward.

[0062] In this embodiment, as Figures 1-2 As shown, the scraper-strip linkage assembly can be used in a floor scrubber. This assembly includes a roller brush 1, a scraper 2, a scraper blade 3, and a transmission mechanism 4. The roller brush 1 is mounted on the frame 5 of the floor scrubber and can rotate relative to the frame 5. The roller brush 1 is the main tool used in the floor scrubber for cleaning the floor. A roller brush motor 102 is installed inside the roller brush 1, which drives the roller brush 1 to rotate and sweep and scrub the floor. The outer circumferential surface of the roller brush 1 in contact with the floor is provided with brush bristles. When the roller brush 1 rotates, the brush bristles allow the cleaning agent to combine with the stains on the floor, thus achieving the functions of sweeping and scrubbing the floor during the rotation of the roller brush 1.

[0063] The scraper 2 is arranged on the frame 5 and can rotate relative to the frame 5. The scraper 2 is provided with an elastic member 12 capable of compressive deformation. One end of the elastic member 12 is connected to the scraper 2, and the other end is connected to the frame 5. The elastic member 12 is in a compressed state in the working state, thus generating an opposite force on the frame 5 and the scraper 2, respectively. The force generated by the elastic member 12 on the scraper 2 can continuously push the scraper 2 to rotate towards the brush roller 1, so that the scraper 2 and the outer periphery of the brush roller 1 can continuously abut together during the working process of the scrubber, thereby realizing the floating state of the scraper 2. The scraper 2 can be made of metal or plastic. Under the constant force provided by the elastic member 12, the outer periphery of the brush roller 1 is always in abutting state with the scraper 2, thereby providing a continuous and constant pressure on the brush roller 1. The dirt and impurities on the brush roller 1 are squeezed out and scraped off, which facilitates collection and prevents the dirt and impurities on the brush roller 1 from entering the inside of the frame 5 and affecting the operation of the scrubber.

[0064] The scraper 3 is arranged on the frame 5 and can rotate relative to the frame 5. The scraper 3 can scrape the water stains remaining on the ground after the brush roller 1 is cleaned by contacting the ground. The scraper 3 can be composed of soft plastic and hard plastic. The hard plastic can fix the scraper 3 at the lower position of the frame 5, and the soft plastic can continuously scrape the water stains on the ground by contacting the ground, thereby ensuring the cleaning effect of the scrubber.

[0065] The first transmission unit and the second transmission unit in the transmission mechanism 4 can be transmission matched. The scraper 2 can drive the first transmission unit to rotate through transmission matching, and the second transmission unit can drive the scraper 3 to rotate through transmission matching. Specifically, the transmission matching among the scraper 2, the scraper 3 and the transmission mechanism 4 is as follows: when the diameter of the brush roller 1 decreases due to use and wear, the scraper 2 rotates towards the brush roller 1 under the continuous force of the elastic member 12, so that the scraper 2 can always abut on the outer periphery of the brush roller 1. At the same time, the scraper 2 drives the first transmission unit to rotate in the movement process, and the rotation of the first transmission unit drives the second transmission unit to rotate, and the second transmission unit drives the scraper 3 to move in the rotation process, so that the contact end of the scraper 3 moves upward.

[0066] Preferably, the transmission mechanism 4 has two groups, and the two groups of transmission mechanisms 4 are arranged on the two sides of the scraper and scraper strip linkage assembly, so that the stress of the scraper 2 and the scraper 3 can be balanced, thereby making the operation of the scraper and scraper strip linkage assembly more smooth.

[0067] Preferably, the elastic coefficient of the elastic member 12 can be adjusted to change the scraping force of the scraper 2 on the brush roller 1.

[0068] By setting the rolling brush piece 1, the squeegee piece 2, the squeegee condition 3 and the transmission mechanism 4 in the squeegee blade linkage assembly, and by the mutual connection and cooperation between the above-mentioned parts, when the diameter of the rolling brush piece 1 is reduced, the good effect of cleaning and collecting dirt and impurities can be ensured, and the compression amount of the squeegee condition 3 at this time is kept consistent with the compression amount at the initial use, so as to reduce the friction between the ground and the squeegee condition 3, reduce the wear of the squeegee condition 3, improve the scraping effect of the squeegee condition 3 on the dirt and impurities on the rolling brush piece 1, and further reduce the resistance faced by the user in the use process, improve the use efficiency of the scrubber.

[0069] Optionally, in an implementation manner of the embodiment, as shown in Figures 3-5

[0070] The first transmission unit includes a first gear 401 fixedly connected to the squeegee piece 2.

[0071] The second transmission unit includes second gears A 4021 and B 4022 and a connecting rod 403, the second gears A 4021 and B 4022 are arranged from top to bottom along the height direction of the rack 5, the second gears A 4021 and B 4022 are both rotationally connected to the rack 5, the second gear A 4021 is engaged with the first gear 401, one end of the connecting rod 403 is in transmission connection with the second gear B 4022, and the other end is in rotational connection with the squeegee condition 3.

[0072] In the embodiment, as shown in Figures 3-5 The first transmission unit includes a first gear 401 fixedly connected to the squeegee piece 2, when the squeegee piece 2 rotates, the first gear 401 also rotates synchronously. The second transmission unit includes second gears A 4021 and B 4022 and a connecting rod 403, the second gears A 4021 and B 4022 are arranged from top to bottom along the height direction of the rack 5, the second gear A 4021 is located above the second gear B 4022, the second gears A 4021 and B 4022 are both rotationally connected to the rack 5, the second gear A 4021 is engaged with the first gear 401 and the rotational direction of the first gear 401 is opposite, one end of the connecting rod 403 is fixedly connected to the shaft center of the second gear B 4022, and the other end is in rotational connection with the squeegee condition 3, when the second gear B 4022 rotates, it can drive one end of the connecting rod 403 to rotate synchronously, thereby driving the other end of the connecting rod 403 to move, and further driving the squeegee condition 3 to rotate.

[0073] ​Preferably, the second gear A 4021 and the second gear B 4022 are two gears that are completely identical, so as to ensure that the transmission ratios of the second gear A 4021 and the second gear B 4022 are the same, so that the force of the squeegee 2 on the rolling brush 1 and the compression amount of the squeegee 3 on the ground can be kept consistent with the beginning.

[0074] Specifically, when the diameter of the rolling brush 1 becomes smaller, the squeegee 2 rotates to the direction of approaching the rolling brush 1 under the action of the elastic member 12, and drives the first gear 401 to rotate clockwise, at this time, the second gear A 4021 rotates counterclockwise, and drives the second gear B 4022 to rotate clockwise, at this time, the connecting rod 403 moves forward, and pushes the squeegee 3 to rotate clockwise, at this time, the squeegee 3 moves upward in the height direction of the frame 5, and the compression amount of the contact end of the squeegee 3 with the ground decreases.

[0075] By arranging a plurality of gears and connecting rods 403 in the first transmission unit and the second transmission unit, the installation space occupied by the first transmission unit and the second transmission unit can be reduced, so as to reduce the volume of the frame 5, so that the scrubber can reduce the volume of the scrubber under the premise of reducing the use resistance of the user, so that the user can move the scrubber more conveniently and labor-savingly.

[0076] Optionally, in an implementation manner of the embodiment, as shown in Figures 6-9 ,

[0077] The first gear 401 is configured as a half gear, the connecting rod 403 includes a first connecting rod 4031 and a second connecting rod 4032, one end of the first connecting rod 4031 is fixedly connected with the shaft center of the second gear B 4022, the other end is rotatably connected with one end of the second connecting rod 4032, and the other end of the second connecting rod 4032 is rotatably connected with the squeegee 3.

[0078] In the embodiment, as shown in Figures 6-9 , the first gear 401 is configured as a half gear, and since the rotation range of the squeegee 2 limits the rotation range of the first gear 401, only the teeth need to be arranged on the side of the first gear 401 close to the second gear A 4021. The connecting rod 403 includes a first connecting rod 4031 and a second connecting rod 4032, one end of the first connecting rod 4031 is fixedly connected with the shaft center of the second gear B 4022, the other end is rotatably connected with one end of the second connecting rod 4032, and the other end of the second connecting rod 4032 is rotatably connected with the squeegee 3. When the second gear B 4022 rotates clockwise, the other end of the first connecting rod 403 drives the second connecting rod 4032 to move to the direction close to the squeegee 3, so as to push the squeegee 3 to move upward in the height direction of the frame 5.

[0079] By setting the first connecting rod 403 and the second connecting rod 4032, the force generated by the clockwise rotation of the second gear B4022 can be converted into a force for moving upward along the height direction of the frame 5, the compression amount of the ground contact end of the squeegee 3 is reduced, and the compression amount of the ground contact end of the squeegee 3 is consistent with the compression amount when it is used for the first time, thereby reducing the resistance that the user faces during use.

[0080] Optionally, in an implementation manner of the embodiment, as shown in Figures 6-9

[0081] The elastic member 12 is configured as a torsion spring, one extending end of the torsion spring is connected with the squeegee 2, and the other extending end is connected with the frame 5.

[0082] In the embodiment, as shown in Figures 6-9 the elastic member 12 is configured as a torsion spring, one extending end of the torsion spring is connected with the squeegee 2, and the other extending end is connected with the frame 5. Since the torsion spring requires a smaller installation space, when the distance between the squeegee 2 and the frame 5 is small, the torsion spring can be arranged in a compressed state between the squeegee 2 and the frame 5. Since the squeegee 2 can rotate relative to the frame 5, the torsion spring in the compressed state can continuously apply a force to the squeegee 2 in a direction away from the frame 5, so that the squeegee 2 can continuously abut against the outer circumferential surface of the roller brush 1 without being affected by the change in the diameter of the roller brush 1.

[0083] By using the torsion spring as the elastic member 12, the distance between the squeegee 2 and the frame 5 can be further shortened while ensuring that the squeegee 2 continuously abuts against the outer circumferential surface of the roller brush 1, thereby further reducing the volume of the frame 5 and making the whole scrubber more compact and portable.

[0084] Optionally, in an implementation manner of the embodiment, as shown in Figures 6-9

[0085] The inside of the squeegee 2 is formed with a water channel, a water outlet 6 is arranged on a side wall of the squeegee 2 close to the roller brush 1 and is in communication with the water channel, the water outlet 6 is used for spraying water to the outer circumferential surface of the roller brush 1, and a water inlet 7 is connected to a side wall away from the roller brush 1 and is in communication with the water channel.

[0086] In the embodiment, as shown in Figures 6-9 ​​As shown, a water channel is formed in the inside of the squeegee piece 2, a water inlet 7 is opened on the side wall of the squeegee piece 2 away from the roller brush piece 1 and is in communication with the water channel, and a water outlet 6 is opened on the side wall of the squeegee piece 2 close to the roller brush piece 1 and is in communication with the water channel. When the scrubber works, the water stored in the frame 5 is mixed with the cleaning agent to form cleaning water, which flows into the water channel in the inside of the squeegee piece 2 from the water inlet 7 and is sprayed onto the roller brush bristles of the roller brush piece 1 through the water outlet 6, so that the roller brush bristles can always be kept wet by the cleaning water during work, avoiding the user's manual wetting operation on the roller brush bristles, thereby improving the efficiency of the roller brush piece 1 in sweeping and scrubbing the ground and providing the user with a convenient and labor-saving use experience.

[0101] By setting the scraping strip body 301 and the second scraping end 302, the scraping condition 3 can maintain the compression amount of the ground contact end consistent with the compression amount when initially used after the diameter of the rolling brush piece 1 is reduced, thereby ensuring the cleaning effect of the scrubber while providing a convenient and labor-saving use experience for the user.

[0102] Optionally, in an implementation manner of the embodiment, as shown in Figures 10-11

[0103] The connecting plate 303 is arranged on the scraping strip body 301, and the second connecting rod 4032 is rotationally connected with the connecting plate 303.

[0105] In the embodiment, as shown in Figures 10-11 The connecting plate 303 is arranged on the scraping strip body 301, and the second connecting rod 4032 is rotationally connected with the connecting plate 303, so that the rotation of the scraping condition 3 is driven by the forward and backward movement of the second connecting rod 4032. The grooves or through holes are symmetrically arranged at both ends of the scraping strip body 301, so that the scraping strip body 301 is rotationally connected with the rack 5 through the connecting piece. The second sealing layer 304 is arranged on the scraping strip body 301 and located between the rack 5 and the scraping strip body 301, and is used to prevent the sewage splashed by the second scraping end 302 when removing the water stains from entering the inside of the rack 5.

[0106] Preferably, the second sealing layer 304 is composed of soft plastic and is fixed on the scraping strip body 301 through the injection molding process.

[0107] Preferably, the second sealing layer 304 extends to the connecting plate 303 direction to form a curved sealing end at one end close to the second connecting rod 4032, and the curved sealing end is located at the gap between the scraping strip body 301 and the rack 5. The curved sealing end is a hollow structure, which can realize extrusion sealing in different directions between the scraping condition 3 and the rack 5 when the scraping condition 3 rotates, so that the gap between the scraping condition 3 and the rack 5 always maintains in a sealed state, thereby further preventing the sewage splashed by the second scraping end 302 when removing the water stains from entering the inside of the rack 5.

The scraper body 301 mainly connects the second scraping end 302 and the second connecting rod 4032, and drives the second scraping end 302 to rotate via the second connecting rod 4032. Therefore, using a rigid component ensures the rigidity of the scraper body 301, making the overall structure of the scraping condition 3 more stable. The second scraping end 302 is made of a soft component. The second scraping end 302 mainly removes water stains from the ground through the friction generated by its deformation under pressure.

[0112] Preferably, the soft component can be soft plastic, which ensures good contact with the ground and can compensate for errors, thereby enabling the removal of water stains from the ground. The hard component can be hard plastic, which can support the second scraping end 302 and the second sealing layer 304.

[0139] Secondly, by arranging a plurality of gears and connecting rods in the first transmission unit and the second transmission unit, the installation space occupied by the first transmission unit and the second transmission unit can be reduced, the volume of the rack can be reduced, the volume of the scrubber can be reduced under the premise of reducing the use resistance of the user, and the user can operate and move the scrubber more conveniently and labor-savingly.

[0140] Thirdly, by setting the first connecting rod and the second connecting rod, the force generated by the clockwise rotation of the second gear B can be converted into a force for moving upward along the height direction of the frame, so that the compression amount of the ground-contacting end is reduced, thereby realizing that the compression amount of the ground-contacting end is consistent with the compression amount at the initial use, and the resistance faced by the user in the use process is reduced.

[0141] Fourthly, by setting the scraping layer, the first sealing layer and the fixed layer, the first scraping end can continuously clean the rolling brush piece while preventing the dirt and impurities peeled off from the rolling brush piece from entering the frame, thereby further improving the working efficiency of the scrubber.

[0142] Fifthly, by setting the water tank and the water pump, the scrubber can store and carry water source, and the cleaning agent added into the water tank can form cleaning water, and the water pump can spray the cleaning water from the water channel to the rolling brush bristles of the rolling brush piece, so that the rolling brush bristles can always maintain a state of being soaked in the cleaning water during work, avoiding the user's manual wetting operation on the rolling brush bristles, thereby improving the efficiency of the rolling brush piece in sweeping and scrubbing the ground and providing the user with a convenient and labor-saving use experience.
